Heteropterus Revista de Entomología 2016 Heteropterus Rev. Entomol. 16(2): 109-113 ISSN: 1579-0681 Otites pagolacartei sp. n.: a new ulidiid species from Spain (Diptera: Ulidiidae: Otitinae) M. CARLES-TOLRÁ Avda. Príncipe de Asturias 30, ático 1; E-08012 Barcelona; España; E-mail: diptera@outlook.com Abstract A new species of the ulidid genus Otites Latreille, 1804 named O. pagolacartei sp. n., is described from northern Spain. It was collected in a holm oak forest by means of wine-beer traps. According to the shape of the male genitalia it is very similar to O. guttata (Meigen, 1830) and O. centralis (Fabricius, 1805). Key words: Diptera, Ulidiidae, Otitinae, Otites pagolacartei sp. n., Spain. Resumen Otites pagolacartei sp. n.: una especie nueva de ulídido de España (Diptera: Ulidiidae: Otitinae) Se describe una especie nueva de ulídido del género Otites Latreille, 1804, llamada O. pagolacartei sp. n., del norte de España. Fue capturada en un encinar mediante trampas con vino y cerveza. Según la forma de la genitalia masculina es muy parecida a O. guttata (Meigen, 1830) y O. centralis (Fabricius, 1805).

Introduction Recently, Carles-Tolrá and Pagola Carte (2013) published a paper on some dipterans collected in the canopy of a Cantabrian holm oak forest from the Basque Country (Spain). Traps with a mixture of red wine and beer as bait were used. Among that material some specimens of Otites Latreille, 1804, that couldn t be identified, were collected. For more details see Carles-Tolrá and Pagola Carte (2013). Such specimens of Otites belong to a new species for science and it is described in this paper. Otites is an Holarctic genus that includes 27 species in the Palaearctic Region (Greve, 1998), 22 of which are known to occur in Europe. In Spain (and the Iberian Peninsula) it is represented by 6 species (Carles- Tolrá and Báez, 2002).

Phallus very long, rolled. Cerci short, rounded, haired, ventral hairs longer. (For the nomenclature the paper by Kameneva (1996) has been followed.) Female as the male. Cerci (Figs. 3b-c) with 4 pairs of short hairs (1 dorsal, 1 dorsoapical, 1 ventroapical and 1 ventral). Type material (193 %% and 224 &&): HOLOTYPE % : Spain: Guipúzcoa: Ataun: Urkillaga (Aralar Parke Naturala), 23.5.-1.6.2012, wine-beer trap, Quercus ilex ilex forest, 614 m, 30TWN6858, S. Pagola Carte leg. PARATYPES: same data as the holotype, 180 %% and 210 &&; same data as the holotype, but 1-14.6.2012, 12 %% and 14 &&. Type material preserved in alcohol (70º). Holotype and 180 %% and 210 && paratypes deposited in the author s collection, 12 %% and 14 && paratypes deposited in the collector s collection. Other material (not types): Same data as the holotype, but 14-26.6.2012, 4 %% and 5 &&, deposited in the I.I. Schmalhausen Institute of Zoology, National Academy of Sciences of Ukraine, Kyiv, Ukraine. Discussion: Following the key by Hennig (1939), Otites pagolacartei sp. n. keys out to O. maculipennis (Olivier in Latreille, 1811), from which it differs by the genitalia and wing pattern (cf. Rivosecchi, 1995: fig. 11). Nevertheless, according to the shape of the male genitalia, O. pagolacartei sp. n. is very similar to O. guttata (Meigen, 1830) and O. centralis (Fabricius, 1805), but they clearly differ by the genitalia, as well as by external morphological characters (e.g. number of dorsocentrals and wing pattern) (cf. Hennig, 1939: figs. 9, 11; Merz, 1996: figs. 1, 2, 8-11; Rivosecchi, 1995: fig. 14, not fig. 12, note the mistake). Biology: Unknown. The specimens were collected in the canopy of a Cantabrian holm oak forest with traps with a mixture of red wine and beer as bait. Distribution: Hitherto only known from the type locality (northern Spain, Basque Country). Etymology: It is a pleasure to dedicate this new species to the collector. Total body length (mm): 6.2-10.1 (%%), 6.5-10.3 (&&); wings (mm): 5.5-8.2 (%%), 6.1-8.8 (&&).
